UNITED STATES PATENT OEEIGEO PHILIP CAREY, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN COMPOSITION COVERING FOR STEAM-PIPES.

Specification forming part of Letters Patent No. 189,301, dated April 10, 1877 application filed Y April 25, 1876.

To all whom it may concern:

Be it known that I, PHILIP CAREY, of Philadelphia, in the county of PhiladelphiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Composition Coverings for Steam-Pipes 5 and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to all classes of steampipes in which it is desirable to retain the heat and prevent its loss by radiation. I propose to accomplish the result by covering the pipes with a non-conducing plastic composition which is cheap and of suicient cohesiveness to 'retain its form and position upon variations in this respect will ,not materially affect the nature of the composition.

, rIhe above-mentioned ingredients, in substantially the proportions given, are placed in any suitable receptacle, and are macerated and brought to a suitable consistency for applying to the pipes, upon which it hardens,

and forms a durable non-conducting cover` lng.

Having thus described my invention, what I claim .is-

A nonfeonducting covering for steam-pipes. consisting of the following ingredients: ine wood-ashes, steamed sawdust, Manila fiber, plasterotparis, white glue, air-slaked lime, all combined in substantially the proportions specified. y

Witness my hand this 15th day of April, A. D. 1.87 6.

PHILIP CAREY.
